That Touch of Mink, Delbert Mann (1962)

Hysterically paranoid movie about a girl from Upper Sandusky (Doris Day) and a zillionaire (Cary Grant) who fall for each other, want to sleep with each other, but can’t because she’s terrified of fooling around outside marriage, and he’s so charmed by her piety he can’t bring himself to violate it. Insane! Can our culture ever really have been like this? Some nice double entendres here and there, but basically just so mind-bogglingly absurd that it’s almost impossible to watch.
